[The characteristics of the genetic relations between different breeds and crossbreeds of sheep].
Frequency of occurrence of antigens belonging to 7 systems of blood groups in four breeds of sheep as well as two crosses of the first generation Tsigai X Ostfrisian; Ostfrisian X Tsigai) has been studied. A phylogenetic affinity between them is presented. Indices of genetic distances between breeds and crosses are calculated. The dendrogram demonstrates the existence of two clusters: the first has been formed with the Caucasian, Ostfrisian, Tsigai breeds and both crosses of the first generation: the second--with Astrakhan breed. The analysis of the results obtained shows that dendrogram constructed with regard for the frequency of blood antigens reflects real relations of the investigated sheep breeds according to the adopted systems.
